Tube connection has never been easier than with John Guest fittings.

NOTE: Fittings and tube should be kept clean, bagged and undamaged before use.

Step 1 - Prepare the connection:

Cut the tube square ensuring it is free of score marks.  We recommend the use of one of the John Guest tube cutters for a perfect cut.  For soft or thin walled plastic tube we recommend the use of a tube insert.

NOTE: Do NOT use a hacksaw.

NOTE: To avoid damage to the 'O' Ring, make sure burrs and sharp edges are removed from the cut end of the tube.

With the fitting clean and undamaged and the tube cut square, you are now ready to make the connection.

Do not insert fingers into the fitting as the stainless steel teeth may cause injury.

Step 2 - Assemble the connection:

John Guest Quick Connection Guide

Push the tube into the fitting, to the tube stop. The collet (gripper) has stainless steel teeth which hold the tube firmly in position whilst the 'O' Ring provides a permanent leak proof seal.

Pull on the tube to check it is secure.  It is good practice to test the system prior to leaving site and/or before use.  It is recommended (and good practice dictates) that you remember to pressure test the completed installation before use.

Disconnecting standard John Guest push-in fittings:
 

John Guest Quick Connection Guide

Ensure system is depressurized before removing fittings.  Push in the collet against the tube stop (center of the fitting). With the collet held in this position the tube can be removed.  The fitting can then be re-used.
